In comparison to similar services, Dropbox offers a relatively large number of user clients across a variety of desktop and mobile operating systems. There are a total of 10 clients, including versions for Microsoft Windows, Mac OS X, and Linux, as well as versions for mobile devices, such as Android, iPhone, iPad and BlackBerry, and a web-based client for when no local client is installed. Dropbox uses the “Freemium” financial model and its free service provides 2 GB of free online storage.
Since the beta tag drop, Dropbox also adds TrueCrypt support, a Rainbow Shell that offers support for extended attributes, selective sync, a new installation wizard, and reduces resource usage. There are both free and paid services, each with varying options.
